单加速度计高旋弹滚转角测量系统误差模型

摘要

针对单加速度计高旋弹滚转角测量系统精度评估方法缺乏的问题，提出了单加速度计高旋弹滚转角测量系统误差模型。该模型中包含加速度计安装位置、安装角度、横轴灵敏度误差。分别用单因素敏感因子合成法和蒙特-卡洛模拟仿真法对单加速度计高旋弹滚转角测量精度的评估结果分别为3.5772°和3.8648°基本一致，仿真结果表明单加速度计高旋弹滚转角测量误差模型是正确的。%In order to study the single accelerometer high spinning projectile roll angle measurement system er-ror and improve the accuracy of measurement,a single accelerometer roll angle measurement error model in high spinning projectile was established.The model contained the error of accelerometer installation location,instal-lation angle and cross axis sensitivity.Respectively using single factor sensitive factor synthesis method and Monte Carlo simulation method to assess the accuracy of single accelerometer roll angle measurement in high spinning projectile,the two methods about the accuracy results was between 3.5772°and 3.8648°,so as to veri-fied the correctness of single accelerometer roll angle measurement error model.
